can anyone help - ive managed to reassign the mame button functions so that i cannot start new games on the emulator(the button to the right of the game pad used to start games and now it brings up menu options) - and the function that you make changes with (in the menu) is not assigned to a button - im working with an ipaq 3765 - any way to restore original mame function settings?Also - two buttons are now assigned to the same function - bringing up menu options
